  • Realistically, the time for nuclear (fission) has past. If we were in the 50s or 60s, and were making a concerted effort to remove fossil fuel energy production, nuclear could have helped us do it. Now, with steadily decreasing renewable energy costs and cheaper and more effective battery storage, it’s a break-even option at best, and takes a long time to implement.

    Fusion has a real chance, provided we can figure it out well enough to do anything with it. It may not be economically viable, and it’s hard to be certain before we actually get it working. Fusion could also be more effective for certain space missions, especially to the gas giants and farther from the sun. Realistically, anything closer than Mars does pretty well with solar.







  • Yeah, the good news is no one has ever suffered permanent damage from verbal abuse, so no problems, right?

    And why is physical violence no-tolerance (except when it isn’t) but verbal violence is a-okay?

    I’m not saying physical violence is okay, and I never have. In fact, I generally go the other direction, saying that physical violence should be a last resort for solving problems, and that those who use it clearly don’t have better tools to solve their problems. And know which groups is known for not having a lot of experience solving problems? Kids. That’s why we have adults supervising them. And training those kids that verbal violence is okay, and a great way to harass your peers, is, to put it bluntly, pretty fucking stupid. And some of those kids learn that a suspension isn’t that big a deal to some of the kids they bully, which is a hell of a lot better lesson than the adults around them were teaching them.








  • It didn’t so much as pull as get stiffer to turn out of the lane. Again, that doesn’t happen if your signals are on, so it’s a good reminder to use your signals, too.

    Like I said, relying on these assists as replacements for proper driving isn’t something I would recommend. You should still be shoulder checking and using your mirrors. My wife’s vehicle has blind spot detection, which turns on an amber light by the mirror. If you’re changing lanes, it’s an obvious indicator that it may not be safe. A more thorough shoulder check can identify if the vehicle is actually at risk for collision. For example, if you just passed a vehicle and are pulling away, the detection light may still be on, but you aren’t at risk of collision. Alternatively, if I thought the lane was clear and decide to change lanes, the light may be on due to a speeding driver who is approaching to pass me in the adjacent lane. The light will be on even though he isn’t in the way yet, and changing lanes could result in an accident. Or maybe someone has been sitting in your blind spot for a few minutes and you decide to change lanes. A quick mirror check indicates you’re safe, but that amber light says maybe not. If your shoulder check doesn’t catch the problem, you probably haven’t done it well enough.

    Again, can be good assistance tools, I don’t think they’re good enough to be replacements yet.






  • Most of these costs are in terms of energy, one of the most plentiful things in space. Also, if we do things right (a huge if, I know), the bigger idea is to bootstrap it by sending enough tools to make the tools you need to extract and refine resources. This doesn’t require a von Neumann machine since we can control them, either directly or remotely. Also, if we are going to extract resources in space, a lot of infrastructure will need to be built first, which is cheaper if we use resources that are already in space. And as the saying goes, the surface of the moon is halfway to anywhere in the solar system.
